DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1900Z August 29, 2005
Central Canada: Patches of detatched smoke, likely originating from the fires over Alaska, were observed this morning across a portion of central to eastern Canada. The areas of smoke covered portions of southern Nunavut and northern Manitoba Provinces, Hudson Bay, northern Ontario Province, and northern Quebec Province. This smoke has become entrained in a large scale circulation center located south of Hudson Bay. Additional smoke may be present over south central and southeastern Canada, but extensive cloudiness associated with the large vortex is preventing detection. Northern Plains/Great Lakes Region: A possible swath of smoke was apparent in early morning GOES-West visible imagery stretching from southern Minnesota across Wisconsin and northern Michigan into southeastern Canada. This possible smoke has also become entrained in the large scale circulation described in the paragraph above. Again, it is not certain that this is an area of smoke, but it does have some characteristics of smoke in the visible channel of GOES. If it is smoke, then it is most likely from either the fires over Alaska or a combination of the smoke from the Alaskan fires and the fires burning across central Idaho. Idaho/Montana/The Western High Plains from Eastern Montana to Northwestern Texas: Moderately dense smoke was visible this morning stretching from the numerous fires burning across central Idaho/western Montana northeastward across a good portion of central and northern Montana and southern Alberta Province of Canada. The smoke then became thinner and more diffuse as it spread southeastward from eastern Wyoming/western South Dakota down into the northwestern Texas panhandle. JS
